SB-E cooling properties

[Magic Carpet]

A question to SB=>SB-E owners.

SB-E is twice the size of regular SB. Do you think/see the bigger die help make the cooling somewhat "easier"?

Thank you.

The heatspreader and die are quite a bit larger, so physically more heat can be transferred away. However in practice most of the time you are limited by the actual cooler itself and so you won't actually see a great deal of benefit from its additional size.

I just got my 3930K today and it is impressively large compared to my aged 1366. But since I intend to cool it with the same water block and radiators its going to run at very similar temperatures.

It has got physical surface advantage... killer looks, very high-end. And seems like nobody has catered your needs yet? That's really bad.

Seriously, would you buy one (2011 exclusive heat-sink) ? ;-p

It was really hard finding any 2011 custom waterblocks at all. The boutique solutions have all but taken over in the watercooling world (H100 and like). A lot of the reviews have compared fairly low end custom kits to the sealed loops and determined there is no advantage to the custom kits. Truth is the last 100Mhz of overclock likely isn't worth getting anyway so why spend £400 getting there.

With 1366 there was a big explosion of innovation and the water loops had become a lot easier to build and buy. But 3 years later and its all the same faces and products. Only one manufacturer has a water block out that is designed for 2011 and it looks just like the 1366 block, so I guess they did the same thing Watercool.de did with my heatkiller 3 and that is create a new screw set/mount for the existing block.

I am happy with my existing block, its incredibly efficient and I am looking forward to my 4.5+ Ghz overclock with fully loaded temperatures in the 50's.

If you think about it though...130W is 130W is 130W. Whether the CPU is a 130W Prescott or a 130W Zambezi or a 130W SB-E.

So from the "cooling" point of view there is little reason to come out with a new block/design just because the pincount has changed.

So really the only reason your HSF or waterblock for your CPU should ever be obsolete is if it was the same footprint as the IHS, and the IHS changed.

In the older days we'd replace our heatsinks because the retention devices were incompatible owing to the socket dimensions. By not so these days.

My H100 fits probably 6 or 7 different sockets with the default retention kit, and the copper block itself is large enough that it could handle a CPU that is 2"x2" in size (i.e. HUGE).

So the only real reason we are left with the need to obsolete our existing cooling when upgrading a CPU is if there truly is a superior thermal dissipation solution out there. That side of things has very slowly changed once we made the heatpipe transition.

Even a NH-D14 can give an H100 a run for the performance, at much less cost. I can't imagine what it will take for me to replace mine (I own both), but I figure they won't be replaced for about 4-5 yrs at the current pace of the industry.

On thing that is different for SBE vs SB is that SB has a lot of silicon that is power-gated and available for shunting away the heat versus the SBE.

I'm referring to the IGP, if its unused and disabled.

I suspect the cores on SBE are much more likely to have lower deltas in the core temps owing to the layout being much more symmetric than that of SB.

And at full load with all cores active I would be surprised if it doesn't run a tad warmer actually because the heat has less aggregate surface area per core to transfer out of the die itself.

Yup. Compatibility is generally not a problem now.

I'm pleased that all I need to mount my EK Supreme HF on a S2011 board is a set of screws and springs. ^_^

I don't know how the cores are layed out and numbered, but with SB, cores 1 & 2 run as much as 10c hotter than 0 & 3 , while with my SB-E, the outer numbers run hotter..

That's true. The 1st and 6th cores run the hottest for me while the 5th core is the coolest.

The compatibility has certain saved me some pounds on cooling the new system.

I know from previous CPU and blocks releases that the manufacturers managed to change the pressure profile and internal water flow of their blocks to improve the cooling for particular models of CPU. The effect is normally only a few C's though so I don't care, just noticing a generally less people talking about and doing custom water cooling loops.

Would be interesting to compare these two, head to head. The H100 should cover the whole IHS, whether it yields lower temps, remains to be seen. I have no required equipment to test, sadly.

2) Noctua's Jakob Dellinger showed off some prototypes at Computex 2011 this summer. One prototype has 20% more surface area than the NH-D14.

Read this.

Read this.

Good read, thanks but that's not SB-E.

Does the D14 not cover the entire IHS of a SB-E? If it does then I don't see why it matters whether the two coolers are cooling a SB or a SB-E.

Heat is heat.

But if the D14 doesn't cover the IHS of a SB-E then yeah, D14 is fail for SB-E in the first place and I wouldn't touch it with a 10ft pole, so why care to do a comparison in that case anyways?

52.5 x 45mm (SB-E) vs 40 x 38mm (NH-D14).

Interesting to see how different square area would affect the temps. Hence, I wanted to see some tests with these two cooling appliances. The "new" old SE2011 has exactly the same base. Let's see what Noctua rep comes back with. I don't fancy closed-circuit wc at all but it would still be nice to observe some figures.
